I know of a guy who fights hard as well, always 741, he said he thinks it is the board, his sample. No idea what to think about this, this seems to happen to people who have very good xtu efficiency normally

also tried a lot of runs yesterday with my retail Z170M and Ripjaws V kit from Michael, but still no luck, not even 741. most of the time 738-739 and rarely 740 http://hwbot.org/submission/3235795_achill3us_xtu_core_i3_6320_740_marks.3840 CL12-12-12-28 1T 220 tight was piece of cake to setup (much easier than on any other board) also tried 3980 same tight but it was much harder to finish a run and did not helped the score. maybe just my W10 32bit is not fast enough.anyway taking a break now, no more time to this bench just wanted to share my experience.
